THE INFLUENCE OF DEMOGRAPHIC HETEROGENEITY ON THE EMERGENCE AND CONSEQUENCES OF COOPERATIVE NORMS IN WORK TEAMS.
基于社会分类理论，研究发现团队人口异质性越大，合作规范越弱，但此效应随时间减弱；与团队其他成员接触越多，异质性成员的规范感知越趋于合作；合作规范在团队构成与工作成果之间起中介作用。
Drawing from social categorization theory, we found that greater demographic heterogeneity led to group norms emphasizing lower cooperation among student teams and officers from ten business units of a financial services firm. This effect faded over time. Perceptions of team norms among those more demographically different from their work group changed more, becoming more cooperative, as a function of contact with other members. Finally, cooperative norms mediated the relationship between group composition and work outcomes.
